Title: Heater
IPC: H01L21/3065
Filed: 1992-03-19
Abstract: PURPOSE:To suppress any cold spot generating on the heating surface by constructing the joint system in such a manner that a lead member will be jointed with a metal selectively. CONSTITUTION:A metal 5 is connected with a terminal 3 and a male screw 7b is fixed between a pair of tying parts 5d. Then the screw 7b can be shifted and fixed freely so as to be aligned with a through-hole 9b. Therefore, even when the embedding position of the terminal 3 in a sintered body is changed, the fitting position of the member 7 can be changed accordingly, thereby it becomes unnecessary to accommodate the tolerance by increasing the dimension of the hole 9b more excessively than that of the member 7. In consequence, the dimension of the hole 9b is merely increased by only matching difference than that of the member 7, resulting in eliminating clearance between both actually. As the result, there occurs no cold spot on a wafer heating surface 1a, thereby improving its thermal uniformity.
